サイトの RSS フィードを XML として取得して表示しようとしていますが、構文エラーが発生しています。コード全体は次のとおりです。

<?php 
   header('Content-type: text/xml');
   $feeds = file_get_contents('http://rss.news.yahoo.com/rss/topstories');
   $xml = simplexml_load_string($feeds);
   foreach ($xml->channel->item as $item) {
      print $item->title;   
   }
?>

私が得るエラーは

XML 解析エラー: 構文エラー場所: localhost/rssfeed.php

誰かが私が間違っていることを教えてくれますか?

ありがとう

ブラウザが有効なxmlを期待しているヘッダーコンテンツタイプを設定することにより、適切なXMLを出力していないため、XML解析エラーが発生します。

これを試して：

<?php 
header('Content-type: text/xml');

//Load your feed (input)
$feed = file_get_contents('http://rss.news.yahoo.com/rss/topstories');
$feed_xml = simplexml_load_string($feed);

//Create a new SimpleXMLElement object (for output)
$xml = new SimpleXMLElement('<?xml version="1.0" encoding="UTF-8"?><news/>');

//Loop each item from $feed_xml->channel->item
foreach ($feed_xml->channel->item as $item) {
    //Create a story node for each item
    $node = $xml->addChild('story');
    //Loop each items & add it to the node if its a title or description
    foreach($item as $key=>$value){
        if($key == 'title'){$node->addChild($key, $value);}
        if($key == 'description'){$node->addChild($key, $value);}
    }
}

//Use dom document to format the output nicly, not required
$dom = new DOMDocument('1.0');
$dom->formatOutput = true;
$dom->loadXML($xml->asXML());

echo $dom->saveXML();
/**Output
<?xml version="1.0" encoding="UTF-8"?>
